The Hyderabad Metro Rail project is an international standard infrastructural construction featuring many technological, engineering and financial innovations.

Communication Based Train Control (CBTC)

Hyderabad Metro Rail features advanced Signaling & Train Control technology Communication Based Train Control (CBTC) for continuous communication between the central control, train operators and the station controllers to ensure better control of train operations and running. The trains will be monitored from the advanced Operation Control Centre (OCC) located in Uppal depot. The Operation Control Centre (OCC) is considered as the primary control centre, as well as back-up control centre for managing the operations during emergencies.

Computer Based Interlocking (CBI) System

Axle Counter based fall-back system is a form of secondary train detection system, deployed across all the three corridors, which is a backup for CBTC. The signaling technology which has been deployed at the depots is based on the redundant Computer Based Interlocking (CBI) system.

Booster Transformers are installed across the three corridors at specified locations for minimizing interference with main communication lines. There are Receiving Substations (RSS) established at Uppal, Miyapur, Yusufguda, & MGBS which receive power supply.

SCADA (Supervisory Control and Data Acquisition) System

Hyderabad Metro also consists of SCADA (Supervisory Control and Data Acquisition) system which offers highest level of support for the purpose of monitoring, controlling and also command. A centralized Operation Control Centre (OCC) based in Uppal Depot controls the entire Power Supply and Traction System Equipment through SCADA.
